Redwing

Hi Chaps

When it comes to constructing model kits such as the Wyvern, Redwing etc, do most builders stick to the plans and use the recommended BA, UNF etc threads or do you convert to metric for ease, availability and so forth?

Cheers, Grubscrew

In the past with the American designs I have maintained the imperial dimensions and stock sizes but changed the UNC to BA and pipe threads to BSP. More recently I have fully converted engines such as the RLE to metric (not just a mathmatical conversion) so the materials are metric and used metric threads which obviously can be cut straight onto the ends of the metric stock.

The half way house is a mix and match which may just entail changing to metric fixings which I have done a few times or a step further you may use metric round stock but still make the parts to the imperial length.

Really depends on what you are happy working with and what material and fixings are readily available.

I generally use metric fastenings where I can.  I never use any US threads because I don’t have any US taps and dies.  My Hoglet and Farm Boy are mostly ISO metric coarse with some BA where that seems more appropriate and some ME threads where fine threads are required.
